Hello,
I'm trying to modify my admin.py from my app "ordis":
from ordis.models import Ordi, Maintenance, OperatingSystem
from django.contrib import admin
#class MaintenanceAdmin(admin.ModelAdmin):
#list_display = (???) here I would like to see my Computer id, and
the OS installed on it
def renvoi_os(Ordi):
#return ("%d" % (Ordi.id)).upper()
return ("%d %d" % (Ordi.id, Ordi.operatingsystemused)).upper()
class MaintenanceAdmin(admin.ModelAdmin):
list_display = (renvoi_os,)
#class OrdiAdmin(admin.ModelAdmin):
admin.site.register(Ordi)
admin.site.register(Maintenance,MaintenanceAdmin)
admin.site.register(OperatingSystem)
That admin.py is associated with this models.py:
from django.db import models
from django.db.models import (Model, BooleanField,
CharField, DateTimeField, TextField, URLField,
EmailField, ManyToManyField, ForeignKey, IntegerField,
FileField, ImageField)
# Create your models here.
class OperatingSystem (models.Model):
operatingsystem = CharField (max_length=30, blank=True, null=True)
class Ordi(models.Model):
architecture = CharField (max_length=30, blank=True, null=True)
operatingsystemused = ManyToManyField(OperatingSystem, null=True,
blank=True)
class Maintenance(models.Model):
ordi=ForeignKey(Ordi, blank=True, null=True)
action = TextField(null=True, blank=True)
When I just call Ordi.id in admin.py (commented line), I get the Ordi
id associated with "Maintenance".
But the line with Ordi.id + Ordi.operatingsystemused gives me back a
(None)
What am I doing wrong??
THanks for your help
Florian
